PERIODIC TRENDS

Front

What happens to atomic size as you move across a period in the periodic table?

Back

Atoms tend to get smaller because the atoms have more protons, which increases the positive charge and pulls the electrons closer to the nucleus.

Front

What is the definition of ionization energy?

Back

Ionization energy is the energy required to remove an electron from an atom.

Front

Why does atomic radius increase as you move down a group in the periodic table?

Back

Atomic radius increases because you add more and more shells (energy levels) as you move down a group.

Front

Which element has the largest atomic radius in Group 18?

Back

Radon (Rn) has the largest atomic radius in Group 18.

Front

What are the elements in Group B of the periodic table commonly known as?

Back

Group B elements are known as Transition Metals.

Front

What is the trend in electronegativity as you move across a period?

Back

Electronegativity generally increases as you move from left to right across a period.

Front

What is the trend in ionization energy as you move down a group?

Back

Ionization energy generally decreases as you move down a group due to increased distance from the nucleus and electron shielding.

Front

What is the relationship between atomic radius and metallic character?

Back

As atomic radius increases, metallic character increases because larger atoms tend to lose electrons more easily.

Front

What is the trend in atomic radius as you move from left to right across a period?

Back

Atomic radius generally decreases as you move from left to right across a period.

Front

What is the significance of the octet rule in relation to periodic trends?

Back

The octet rule explains why elements tend to gain, lose, or share electrons to achieve a full outer shell, influencing trends like ionization energy and electronegativity.
